java調用第三方應用程序

1. java調用第三方應用使用 ProcessBuilder 對象來調用   

例子位置:

  xc-service-manage-media-processor/test/TestProcessBuilder

 

//建立processBuilder對象
        ProcessBuilder processBuilder = new ProcessBuilder();
        //設置第三方應用程序的命令
//        processBuilder.command("ping","127.0.0.1");
        processBuilder.command("ipconfig");

        //將標準輸入流和錯誤流合併
        processBuilder.redirectErrorStream(true);
        //啓動一個進程（至關於在命令行中輸入命令）
        Process process = processBuilder.start();

        //經過標準輸入流來拿到正常和錯誤的信息
        InputStream inputStream = process.getInputStream();

        //轉成字符流
        InputStreamReader reader = new InputStreamReader(inputStream,"gbk");
        //緩衝
        char[] chars = new char[1024];
        int len = -1;
        while ((len = reader.read(chars))!=-1){
            String string = new String(chars,0,len);
            System.out.println(string);
        }
        inputStream.close();
        reader.close();
